三层网管交换机不开启DHCP,怎么设置AC为旁路模式,瘦AP获取不到IP地址。组网不了。
(0)
最佳答案
瘦AP需要有地址才能注册上AC,如果不想要自动获取可以进到AP手动配置地址或者组网里面找其他设备开启dhcp服务器功能。参考无线轻轻松松配案例-WAC380系列产品旁路部署配置AP二层注册及无线加密(WEB版)

您好,请知:
关于AC的旁路,以下是部署要点,请参考:
1、在AP接入的交换机上也创建VLAN,将VLAN划分到端口,确保基础网络可达。
2、在AC上配置WLAN的参数比如服务模板、AP注册。
3、可以另外的部署一台DHCP服务器,发现建立CAPWAP隧道
以下是配置案例,请参考:
AP通过DHCP选项方式从DHCP server上获取AP和AC的IP地址,发现AC并与AC建立CAPWAP隧道连接。
图1-3 通过DHCP发现方式建立CAPWAP隧道典型组网图
(1) 配置DHCP server
# 使能DHCP服务器功能。
<DHCP Server> system-view
[DHCP Server] dhcp enable
# 配置DHCP地址池1。
[DHCP Server] dhcp server ip-pool 1
[DHCP Server-dhcp-pool-1] network 1.1.1.0 mask 255.255.255.0
# 通过自定义选项的方式配置Option 43的内容,为AP指定AC的IP地址1.1.1.3,注意Option 43选项内容中最后四字节为01010103(1.1.1.3),即为AC的IP地址。
[DHCP Server-dhcp-pool-1] option 43 hex 800700000101010103
[DHCP Server-dhcp-pool-1] quit
[DHCP Server] quit
(2) 配置AC
# 配置AC的VLAN-interface 1的IP地址为1.1.1.3/24。
<AC> system-view
[AC] interface vlan-interface 1
[AC-Vlan-interface1] ip address 1.1.1.3 24
# 创建ap1,配置序列号为210235A1BSC123000050。
[AC] wlan ap ap1 model WA4320i-ACN
[AC-wlan-ap-ap1] serial-id 210235A1BSC123000050
[AC-wlan-ap-ap1] quit
# AP启动后,DHCP server会给AP自动分配IP地址1.1.1.2,同时由于Option 43选项携带AC的IP地址1.1.1.3。AP拥有了自动分配的本地IPv4地址和需要建立关联的AC的IP地址1.1.1.3,就会开始发现AC的过程并建立CAPWAP隧道。
# 查看AP的详细信息,可以看到AP与AC成功建立隧道连接并进入Run状态,发现方式为DHCP选项方式。
